  • Spinning was conducted by repeating the procedure of Example 1 except that the spinning oil used was spinning oil A-2, the polymer ejection rate per single ejection hole was 4.1 g/min, the winding speed of the undrawn yarn was 450 m/minute, the draw ratio was 4.55, and the oiling was conducted so that the spinning oil coating weight would be 0.6% to obtain a pirn-shaped package of 22 dtex nylon 66 monofilament.
  • the resulting nylon 66 monofilament was evaluated for the abrasion tension, amount of static electricity generated, spinning oil coating weight, upper limit of the warping speed, weaving productivity, and vertical line quality. The results are shown in Table 3.
  • Nylon 66 chips having a relative viscosity (98% sulfuric acid) of 2.8 were melted at 293° C., and the molten resin was supplied to a melt-spinning pack with the polymer ejection rate per single ejection hole adjusted to 2.4 g/min.
  • the yarn was spun by ejecting the resin from the spinneret and cooled to a temperature of up to 40° C. by a uniflow chimney which sprays cold air from one direction.
  • the yarn comprising 6 filaments was divided into each yarn, and oiled with a spinning oil F-1 by an oiling roller-type oiling device with the speed adjusted so that the spinning oil coating weight would be 0.6%.
  • the yarn was then wound 3.5 times on the first godet roller at 768 m/minute and then 4.5 times on the second godet rollers which has been heated to 170° C. to conduct the heat treatment, and in the meanwhile, the yarn is drawn 4.05 times between the first godet roller and the second godet roller, and wound at a winding speed of 3000 m/minute by a cam traverse-type winding system to thereby obtain a drum-shaped package of 8 dtex nylon 66 monofilament.
  • the resulting nylon 66 monofilament was evaluated for the abrasion tension, amount of static electricity generated, spinning oil coating weight, upper limit of the warping speed, weaving productivity, and vertical line quality. The results are shown in Table 3.
  • the vertical line quality and weaving productivity were excellent in Examples 1 to 9 with low abrasion tension and low amount of static electricity generated.
  • the vertical line quality and the weaving productivity were inferior in the Comparative Examples 2, 3, and 4 with high abrasion tension and low amount of static electricity generated.
  • Weaving productivity was inferior in Comparative Example 1 where the abrasion tension was low while the amount of static electricity generated was high.
  • the vertical line quality and the weaving productivity were inferior in Comparative Example 5 where both abrasion tension and amount of static electricity generated were high.
